Noise in Boston
The Air Pollution Control Commission works to maintain healthy air quality and noise levels in the City.
The Boston Municipal Code sets standards for reasonable noise levels. It also sets maximum acceptable noise levels for different times of day. An unreasonable level of noise is:
- anything louder than 50 decibels from 11 p.m. to 7 a.m., or
- anything louder than 70 decibels at any time, except for permitted construction.
The Commission has developed regulations that apply to residential, business, and industrial districts. Our Commission and the Boston Police Department work together to enforce the rules on noise. If you have a noise complaint, you can report it to the appropriate authority using the “Contact” section below.
